As a Protestant, I am not too big on a special priesthood either, especially for purposes of confession. However, I feel you are way too harsh in your condemnations of the RCC. Even if the bread and wine do not actually become the body and blood of Jesus, the very fact that millions believe such can have a powerful positive impact upon their lives, because it makes them feel very close to Jesus and his sacrifice for us. I see nothing wrong in believing something that by all evidence, was taught and believed from at least 150 A.D. onward and probably at least since 100 A.D. For me, the evidence is too slim to say for sure what was believed in the 1st Century, but the doctrine may well go back to the beginning.
If the bread and the wine somehow mysteriously became the actual body and blood of Christ after taking it - I would have no problem with that. Indeed, it's not something I could even understand if it is so.
I don't see it in scripture. But I am perfectly willing to grant that it hurts no one to believe that it does literally change. In fact, you are right in saying that believing such would make for a very meaningful time with the Lord and I doubt very much that He has a big problem with believing it even if it isn't as believed.
After all - it's a matter of the heart and not absolutely correct doctrine.
My problem is with an earthly organization which claims that salvation itself comes by the taking of the already changed elements and that they alone hold the power to so change them.
No change = no sacrifice. No partaking of sacrifice = no salvation. No special priesthood and associated ceremony and words = no nothing.
Mother Theresa's view of these false teachings is exactly the thing which caused her torment of her soul.
She never traveled anywhere without her special priest who could give her salvation before she passed on in case of illness or trauma. She lived in mortal fear of not only thousands of years in Purgatory which supposedly awaited her - but of an eternity in Hell if things were not done for her exactly as taught in Catholicism.
These things and others related to them are the "blasphemy" I speak of and not the simple beliefs by Catholics concerning what happens to the bread and wine.
No doubt I have practices and beliefs which are off somewhere along the line. I'm quite sure I'm forgiven for them where ever they occur. But then - I have assurance that I am "saved" not just some cultish hope that I may be if I and those over me do things exactly right.
The blasphemy is the preaching of a false gospel of which, in the case of Rome, the transubstantiation performed by a special priesthood is an integral part.
So long as doctrinal differences do not interfere with a simple apprehension of the gospel I am willing to enter into intramural debate without harshness. But the moment the simple gospel of salvation itself is compromised - I take on another tone and make no apologies for it.
My "harsh" assessment of those who do not hold the exact doctrine I understand does not stem from an unfairly critical spirit. It stems from a Godly anger at those who shut up the Kingdom of God to those less powerful or educated than they are.
